Sanctioned by IMSA, and organized by Ford Performance Racing School (FPRS) Motorsports, Mustang Challenge allows drivers up to FIA silver ratings to compete on a level playing field against other Mustang Dark Horse R cars.

Each IMSA-sanctioned event will feature two 30-minute practice sessions, one 15-minute qualifying session and two 45-minute sprint races. The field will be split into two classes – Dark Horse and Dark Horse Legends, the latter being an optional classification eligible to bronze-level drivers 40 years old and over.
